[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figures 1 to 4As shown, a knob-opening anti-counterfeiting lock of the embodiment of the present invention comprises a pair of lock bodies 1; an articulated seat 12 is fixedly connected to the end of the lock body 1; a plum blossom pin 13 is detachably mounted between the pair of articulated seats 12; a connector 14 is fixedly connected to the other end of the lock body 1; an anti-counterfeiting ring 15 is detachably mounted in the middle of the pair of connectors 14; a plurality of first limiting teeth 16 are fixedly connected to the inner side wall of the anti-counterfeiting ring 15; a plurality of second limiting teeth 17 are fixedly connected to the side wall of the connector 14; a pair of screws 14 are fixedly mounted in the middle of the pair of connectors 14. The knob nut 18 is connected to the anti-counterfeiting ring 15; the middle part of the knob nut 18 facing the anti-counterfeiting ring 15 is provided with an anti-counterfeiting groove 19; the side wall of the anti-counterfeiting ring 15 is fixed with a plurality of anti-counterfeiting teeth 110; when working, the plum blossom pin 13 is installed in the middle of a pair of hinged seats 12, so that a pair of lock bodies 1 can be rotated and opened and closed around the axis of the plum blossom pin 13, and the pair of lock bodies 1 are put on the position where the lock is required to be installed, so that the locked object cannot be easily opened by conventional means, and then the anti-counterfeiting ring 15 is put on the middle of the pair of connectors 14 The first limit tooth 16 and the second limit tooth 17 are in contact with each other, and the anti-counterfeiting ring 15 is able to continue to move due to the elastic deformation of the first limit tooth 16. After the fastening is completed, the second limit tooth 17 will press against the first limit tooth 16, making it difficult for the anti-counterfeiting ring 15 to rotate in the opposite direction. When the knob nut 18 is turned, the knob nut 18 is removed from the connector 14. At this time, the anti-counterfeiting teeth 110 will be squeezed and broken by the side wall of the anti-counterfeiting groove 19. If multiple anti-counterfeiting teeth 110 are found to be in a broken state before opening, it means that the lock has been opened in advance. Through the above structure, an anti-counterfeiting mechanism is added to the lock. By observing whether the anti-counterfeiting teeth 110 are in a complete state before opening, it is convenient to determine whether the container closed by the lock has been disassembled, thereby reducing the occurrence of items in the container being replaced.

[0022] like Figure 1 As shown, the lock body 1 can be made of zinc alloy, aluminum alloy or plastic; due to the wide range of supporting materials, the surface craftsmanship is also more diverse, and the color and shape can be changed to better meet customer needs.

[0023] like Figures 1 to 4 As shown, the anti-counterfeiting ring 15 and the first limiting tooth 16 are made of plastic; the knob nut 18 is made of plastic; because the anti-counterfeiting ring 15 and the knob nut 18 need to be forced in, the anti-counterfeiting ring 15, the first limiting tooth 16 and the knob nut 18 need to be elastic, and the plastic material can ensure a more stable structure and better anti-counterfeiting performance.

[0024] like Figure 2As shown, the plum blossom pin 13 is made of food-grade 304 stainless steel; as a fixing part and a stabilizing shaft, 304 stainless steel has better strength, is hygienic and environmentally friendly, can be used for a long time, and can be recycled.

[0025] like Figure 3 As shown in the figure, a plurality of anti-slip grooves 111 are provided in the middle of the knob nut 18; the plurality of anti-slip grooves 111 are densely distributed in the middle of the knob nut 18; during operation, when the size of the knob nut 18 is small, the contact area between the knob nut 18 and the fingers is small when the knob nut 18 is pinched and rotated, which makes it easy to slip and difficult to squeeze and break the anti-counterfeiting teeth 110. By setting a plurality of anti-slip grooves 111, the friction between the knob nut 18 and the fingers can be increased, the occurrence of slipping can be reduced, and the convenience of use of the device can be improved.

[0026] During operation, the plum blossom pin 13 is installed in the middle of a pair of hinged seats 12, so that the pair of lock bodies 1 can be rotated and opened and closed with the axis of the plum blossom pin 13, and the pair of lock bodies 1 are placed at the position where the lock is required to be installed, so that the locked objects cannot be easily opened by conventional means, and then the anti-counterfeiting ring 15 is placed in the middle of a pair of connectors 14, and then the knob nut 18 is placed in the middle of the pair of connectors 14, and the multiple anti-counterfeiting teeth 110 are extended into the anti-counterfeiting groove 19, and then the knob nut 18 is turned to drive The anti-counterfeiting ring 15 rotates and extends toward the connecting head 14. When the first limiting tooth 16 and the second limiting tooth 17 contact, the elastic deformation of the first limiting tooth 16 allows the anti-counterfeiting ring 15 to continue to move. After the tightening is completed, the second limiting tooth 17 will press against the first limiting tooth 16, making it difficult for the anti-counterfeiting ring 15 to rotate in the opposite direction. When the lock needs to be opened, turn the knob nut 18 to remove the knob nut 18 from the connecting head 14. At this time, the anti-counterfeiting tooth 110 will be squeezed and broken by the side wall of the anti-counterfeiting groove 19.
